  • Electrostatically actuated device
    Patent number: 11635235
    Abstract: A device including a bottom electrode on a substrate and a top electrode on a substrate separated by a fixed distance from each other. Semi-insulator layers with proper electrical conductivity are attached to the bottom and top electrodes. Disposed between the substrates is a flexible S-shaped polymer stack having electrode layers with one end of the stack attached to the top substrate and the other end in contact with the bottom substrate. When a voltage is applied between the stack and the electrode layer on the bottom substrate, the stack is induced by electrostatic force to deflect in a rolling wave-like motion. While the voltage applied between the stack and bottom electrode is turned off, the static charges on the semi-insulator layer can move away quickly due to the proper electrical conductivity of the semi-insulator layer.

  • Controlling a reference signal pattern based on doppler parameters
    Patent number: 11637730
    Abstract: Aspects of the disclosure relate to wireless communication networks having a capability of controlling the mapping of reference signals onto a carrier based on one or more Doppler parameters. A demodulation reference signal (DMRS) is mapped to a carrier according to a pattern based on one or more Doppler parameters, such as a Doppler frequency and/or a rate of change of channel conditions. In a further example, if an initial transmission of an information packet fails due to a high Doppler scenario, the probability of success of the retransmission may be improved by altering the DMRS configuration to account for the high Doppler scenario. Other aspects, examples, and features are also claimed and described.

  • Incoming query distribution using parallel processing
    Patent number: 11637931
    Abstract: The distribution of incoming queries to a customer interaction center agent group is parallel processed amongst agents of that group to improve queue wait times. A threshold number of queries that may be processed by agent devices associated with the agent group at a given time are defined based on a number of agents of the agent group that are available at the given time. In response to determining that the number of queries is satisfies the threshold number of queries based on the number of agents that are available at a current time, a number of queries awaiting processing are distributed to one or more agent devices of the agent group. The threshold number of queries may be based on half of the number of agents that are available at the given time.

  • Methods for determining prediction value, encoder, and decoder
    Patent number: 11638015
    Abstract: Methods for determining a prediction value, an encoder, and a decoder are provided. Reconstructed values of neighboring samples of a current block are acquired, and then filtered to obtain a reference value set of the current block. When a size of the current block is smaller than a preset threshold value, a first constant value is calculated according to a bit depth value of a luma component of a sample in the current block. A difference between the first constant value and a first reference value in the reference value set is determined as a first prediction input value in a prediction input value set. Other prediction input values in the prediction input value set other than the first prediction input value are determined according to the reference value set. Prediction values of samples at specific positions in the current block is calculated and then filtered.
